I just picked this up before class and played for about 3.5 hours afterwards and it's a great music game with a great soundtrack of great songs to play. The last few on easy mode get a little confusing with quick reflexes needed to do extremely well on the Queens of the Stone Age track, Motorhead, and the last track that I'm blanking out on. I highly recommend it to rock fans, Harmonix fans, and probably Guitar Freaks fans, as well.
